Description
Technical field
The present invention relates to refuse reclamation technical field, especially a kind of paper plant's bottom ash regeneration manufacture is at biomass fuel
The technique of material.
Background technique
Pulping and paper-making raw material is needed by washing impurity-removing, if timber and non-wood fiber melting process are to wood chip, reed piece and grass
After the raw materials such as piece are washed, the biomass waste residues such as a large amount of sawdusts, reed slag and dust can be generated.These impurity are more and more, at
For a great problem for polluting environment.There are two types of the waste sludge from paper mill isolated in production process: one is dry method except the waste residue gone out, is
Some light dust are in the majority, and water content is not high, but use value is lower.Another kind is that wet process removes waste residue out, water content
Very up to saturation, it is necessary to carrying out high-efficiency dehydration drying and other treatment could efficiently use, this kind of impurity after drying and other treatment calorific value compared with
Height has higher reclamation utility value.The calorific value of general 2 tons of over dry waste residues is suitable with 1 ton of standard coal, and energy-saving benefit is very
It is considerable.
Biomass molding fuel is because of its special synthesis technology and is widely applied field and has been to be concerned by more and more people,
Its investigative technique also will be important topic that Chinese future development biomass energy is faced.Paper mill utilizes regrown material papermaking
When, a large amount of waste material, including twisted rope, secondary stock, waste plastics etc. can be generated in production process, the processing for these waste materials is existing
They cannot be carried out classification recycling well by some treatment process.
Existing technology is that the bottom ash that paper mill is generated passes through the method for washing, light plastic and the paper pulp of remnants
It sorts out.Remaining waste residue just passes through the method processing of landfill and burning.This processing method for paper plant's waste residue, a side
Face can not recycle the metal material in waste residue, waste of resource；On the other hand, only after simply sorting, residue is useless
Slag is filled and is burned, and is wasted the resource in waste residue, also be polluted environment.
